Bioaccumulation and chemical form of chromium in Leersia hexandra Swartz.
The chromium bioaccumulation ability of Leersia hexandra was assessed and the chromium distribution in the deferent chemical forms in plant tissues was determined. The hydroponic experimental results indicated that the maximum chromium concentration in the dry leaf matter of Leersia hexandra reached 4302 mg kg(-1). Chromium treatment could significantly increase the proportions of oxalic integrated chromium in leaves and residue chromium in roots, which might be related to the high resistance and bioaccumulation capacity for chromium in Leersia hexandra.
